To all whom it may concern:

\ Be it known that I, CHARLES W. HUBBARD, a citizen of the United States, residing at Weston, county of Middlesex, State of Massachusetts, have invented an Improveand Twisting Apparatus, of which the 0 lowing description, in connection with the accompanying drawing, is a specification, like characters on the drawin representing like parts.

' his invention relates to an apparatus for winding and twisting yarn and is in the nature ofan improvement on the apparatus shown and described in my co-pendmg application Se. No. 25,386, filedMay 3, 1915,

some of the purposes of the improvement being to simplify the construction shown in said application and to provide a device which is thoroughly balanced and capable of high speed operation without jar or vibration.

In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel fea tures will bepointed out in the appended claims.

Figure 1 of the drawings is a vertical sectional view of a device embodying my in-,

vention; I

Fig. 2 .is a view taken at right angles to Fig. 1 with a portion of the casing broken out to better show the construction;

Fig. 3 is a section on the line 3-3; Fig.- 2. Fig. 4 is a section on the line H, Fig. 2. The device herein illustrated is similar to that shown and described in my said copending application Se. No. 25,386 in that it comprises a yarn receiver in the form of a receptacle 1 in which the yarn mass 2 is built up in transverse layers by means of a winding head including a winding plate 3 that rests on the yarn mass and has a slot 4 therein thro h which the yarn 5 is delivered,

.means being provided for rotating the yarn container 1 and winding plate 3 at difierent speeds to effect the winding operation. The winding plate 3 is shown as secured to a head 6 by means of posts or pillars 7, said head being rigidly secured to a shaft 8 and driven by means of a suitable gear 9, the shaft being hollow so as to permit the yarn 5 to be ,led therethrough. The yarn is given a traversing movement as it is laid by means of a vibrating yarn guide 10, as provided for in said application. The yarn container 1 is provided with a false bottom 11 on which the yarn mass is built up and whichis capable by any suitable means and at different speeds so as to secure the desired relative movement between the yarn container 1 and the winding plate 3, all as provided in said application.

Associated with the yarn guide is a vibrating compensatin member 16 having an eye through which t e yarn 5 extends before it is delivered to the yarn guide 10, the object 'of the compensating member being to cause the yarn to be drawn through the spindle or shaft 8 at a uniform speed, regardless of whether the yarn guide is delivering yarn near the center or near the air cumference of the thread mas. It will be understood, of course, that when the yarn guide is delivering yarn at the circumference of the am mass, said yarn will be laid more rapi y than when the yarn guide is delivering the yarn near the center of the. yarn mass, it being assumed that the yarn mass and winding plate have a fixed relative speed. The compensating member 16 co-acts with the' yarn guide 10 to draw surplus yarn through the spindle when the yarn guide isfswinging toward the center, and is thus delivering yarn at a decreasing speed, and to, give up said surplus yarn when the yarn guide is moving toward the circumference and is thus delivering yarn at a progremively-increasing speed, the result being a uniformdelivery of yarn through the spindle 8.

The arn guide 10 is in the form of an arm secure to a rock-shaft 17 journaled in a bearin 18 formed on the head 6. This rockshaft 1 is given its oscillatory movement by means of a cam 19 which is rotatably mounted on a stud 20 rising from the head, 6, said rock-shaft having an arm 21 provided with a roll which operates in the groove of said cam 19. The compensating member 16 is similarly o erated, that is it is secured to and depen from a rock-shaft 22 journaled having an arm 24 which operates in a cam.

groove ina cam member 25" that is 'rotatably mounted on a stud 26 rising from the head 5 6. These cams 19 and are rotated partly from the shaft 8 and partly from the sleeve 14. Said cams have integral therewith gears 28 and 29, respectively, which mesh with and are driven by a gear 27 that is loosely mounted upon the shaft 8. The gear 27 is driven from the sleeve 14 and this may be accomplished either by making said gear rigid with the shaft or by. connecting the gear thereto. 1 In the illustrated embodiment of 5.my invention the gear 27 is provided with clutch teeth which engage corresponding teeth 31 formed on the lower end. of the sleeve 14 so that said sleeve and gear will rotate in unison. Since the sleeve 14 and shaft 8 are rotating at different speeds, the result will be a differential motion which will be transmitted to the cams 19 and 26, thereby giving the yarn guide and compensating member their desired vibratory movements. This construction is not only. simple and one which embodies few parts, but it also has the advantage that the cams and compensating member and yarn guide are so disposed as to make a perfectly balanced structure, the cams being situated directly opposite each other and the yarn guide and compensatingarm being also situated directl op osite each other. As a result the win ing cad. is in perfect balance and can be. run at'a high speed without developing any particular vibration. The bearing for each of the rock-shafts 17 and 22 is provided with an opening through which the stem of the yarn guide or 'compensat' member extends, the wall 41 of said openmg being so disposed that the stem of the yarn guide or compensatin member will have bearing thereagainst. hese rock shafts are also preferably of such a length that the inner Q 5 ends 32 thereof bear against the end wall 33 of the hearing when the rock shaft is prop erly positioned. This construction has the advantage that it facilitates the assembling,

of the parts and also that the stein of'the 5e yarn guide or compensating memberacts as a means to retainthe corresponding rock shaft in place.

In assembling. the parts each rock shaft is inserted into its bearing from the o 11 end thereof until the end of the rock s aft engages the endwall 33, at whichtime the rock shaft is properly positioned so. that the stem of the compensating member or yarn guide can be inserted into the aperture formed m 80 the rock shaft for the reception thereof. The

engagement of the stem of the yarn guide or compensating member with the wall 41'holds the rock shart in position.

34 designates a casing or cover which is as screw-threaded to the head 6 and which inconstruction is such that. this casi .of spring tention to lubricate the parts by suppl ing the interior of the casing 34 with oil, an thfi wit the head forms an oil chamber which securely holds the oil and prevents it from escaping. The position of the rock shafts 17 and 22 is such: that the centrifugal force will tend to throw the oil toward the outer end of the shaft and thus while these shafts will be sufiiciently lubricated, it will not be v possible for any 011 to work its way along the shaft toward the inner end thereof in suflicient quantities to drop down through the opening 40. v

The yarn container 1 is constructed to ex-' tend some distance above the winding plate 3 and it may be detachably secured at its 35 upper edge to the housing or holder member 13 in any suitable way; I have herein shown the upper end portion 45 .of the container 1 as made somewhat thicker than the body of the container and as connected to the lower end of the member 13 by a bayonet joint lock or an ordinary breech lock, as

shown at, 46. This thickened upper portion of the yarn container is provided with a ertures 36 situated just above the win ing plate and through which any lint that accumulates may escape. When the .yarn

'. container has been filled and is removed out any danger that the top of thejyarn mass will be forced out'of the yarn container. entirely and thus become disarranged. It will be seen that the mechanism herein illustrated is extremely simple and is perfectly balanced thereby making it especially adapted for high. speed operation. Moreover, all

of the operative parts are entirely inclosed.

The yarn mass is built up in the yarn container on a yarnj support herein shown as a plate 5 1 resting 'on an expansible plug 52. The expansible plug 52 is made in two sections which are expanded outwardly against the walls of the yarn container by means 54. The friction of the expansible plug 'against the walls ofthe yarn container affords suflicient resistance to the downward movement of the yarn mass to cause the yarn to be compactly laid.

The plate51 is shown as provided with a central depending portion which is received bitween the trio sections t1(if the expansible p u and whic supports 54.
